CocKERELii, 1). Cluck-lji.st New Mexico of tlte A/iriciil- Experiment Station. Since the publication of the Check-List* in 1896 no k>ss than three hundred and twenty-two species have been added. A few of these are ohl species which had been accidentally omitted or improperly reduced to synonyms, but the number of actually new species is very great, and bears witness to Forty species, given as valid the activity of coccidologists. in the Check-List, are here reduced to varieties or synonyms. As before, I have included a number of names of species (mostly by Green) which I know to })e either in press or awaiting very early publication. The group Idiococciiue has been abandoned and merged into Coccince. The Coccincc could very well be divided into two subfamilies and perhaps four tribes, as follows : (A.) Coccince. and the Newly hatched larva with rows last of dorsal spines, antennal joint usually short. Anal ring hairless. (("orr;/.s, etc.) Anal ring hairy, hairs normally (1.) Coccini. (2.) Eriococcini. 8. {Eriococciia, etc.) (B.) l)(irfi/lo])iin(C. Newly hatched larva without dorsal spines, last antennal joint usually long. (1.) Spluerococcini. (2.) Dactylopiini. Anal ring hairless. {SpluerococcHH.) Anal ring hairy, hairs normally G. {Dactylojiius, etc.) Species which were in the original list, here repeated to indicate varieties, synonyms, etc., have the original numbers.

I leave Mr. Cooley to publish the generic characters and classify the species. (17.) Mr. Cooley is responsible for the synonymy. (18.) According to Mr. Cooley. (19.) Mr. Cooley finds that specimens of C. prmiicola from Mr. Maskell are Diaspis amygdali. It is just possible that Maskell accidentally mixed the THaspils with a genuine Chionaspi.H, however, and \\\tA pmnicola may still be valid. (20.) This could very well pass tox AgpidloUi>i awt/hM. did it not have a D«a.s/)i.s male scale.' D. piricola, in Kurope, was long confounded with Aspidiotus ostrec^ormis.
